DEVASTATED Myleene Klass is pleading with her estranged ­husband Graham Quinn to give their marriage another try.

Security firm chief Quinn, 38, walked out on stunned Myleene and their two girls on his wife’s 34th birthday in April.

But she has told friends she is desperate for him to “come to his senses” and make their six-month marriage work for the sake of their young daughters.

The couple – who first started dating 11 years ago when he was a security guard for Myleene’s old pop band Hear’Say – speak daily on the phone.

A pal told The People: “Myleene can’t work out why Graham left. She has been asking him time and time again to come back. She feels it’s possible to win him back.” The pair got engaged in 2005 but only got hitched last October. But six months later he walked out on her and their girls Ava, four, and Hero, one.

Yesterday Myleene told Twitter ­followers: “Thank you all of you for the thoughts and msgs of support for me and my girls. They’ve given me comfort, courage and hope. #strongmamas X”
